Hi All,
I have 7210 variant of Xeon Phi. Using BIOS, if I choose Quadrant (or Hemisphere - not sure what it means for cluster mode) I get node log which I think belongs to All-2-All.
Does that mean 7210 version of Xeon Phi doesn'tsupport Quadrant mode and it's switching to default mode of All-2-All?
